PeopleCode FieldEdit Event

FieldEdit PeopleCode fires for the field and the row that just changed. So, to validate the input entered by a user into a field, you may write PeopleCode in the FieldEdit event of that particular filed.

This is the place you should be using the warning and error statements to convey appropriate messages to the user. However, to check for consistency across fields on a page, PeopleSoft recommends using PeopleCode SaveEdit event.
